Hello

Thank you for your query. Do you want to show advertisement at the starting of the video? Could you kindly share a bit more details for better understanding.

I cannot give you much more information. I signed a contract with an ad provider and the only information they passed was to add the above code to VAST code to trigger an ad displaying prior to the actual video starting.

Can you kindly contact your ad provider, that would be convenient as we don't have such option to do that.
